No keeper has kept more clean sheets in the Premier League than Jack Butland this campaign (7, level with Joe Hart). He also has the best saves to shots ratio in the Premier League so far in 2015-16 (82.5%).

The Potters have not conceded a Premier League goal while Ryan Shawcross has been on the pitch this season (497 minutes).

Stoke City have kept seven clean sheets in their last nine Premier League games.

West Ham have won just two of their last nine Barclays Premier League home games (W2 D4 L3), but are unbeaten in the last six.

The Hammers have, however, gone six Premier League games without victory (L2 D4) – their longest winless run since March (seven matches).

Stoke have scored just six goals in their last 11 Premier League away trips and conceded just nine.

Stoke City’s Premier League games have seen just 27 goals scored this season – fewer than any other club.

The Hammers have kept back-to-back clean sheets twice this season (also did it v Liverpool and Newcastle in August/September).
